Claims

[Scope of Claim for Utility Model Registration] 1. A variable resistor in which a rotor equipped with a slider that can freely slide on the surface of a resistor substrate is rotatably housed in a case, and a fin portion having a recess at the root. A rotary variable resistor with a bump-crash prevention configuration in which the rotor is provided in the shape of an impeller on the outer periphery of the rotor. 2. A backlash prevention structure for a rotary variable resistor according to claim 1, wherein protrusions having no concavities at the roots are formed in the shape of an impeller at equal intervals on the outer periphery of the rotor. 3. A backlash prevention structure for a rotary variable resistor according to claim 1, wherein the recess of the protrusion provided on the outer periphery of the rotor is a cut groove formed in a direction opposite to the protrusion direction of the fin. 4. A backlash prevention structure for a rotary variable resistor according to claim 1, wherein the rotor is made of an elastic member.
